The high-pressure cleaner does not know whether you have known it or not, which has brought great convenience to our cleaning work. What is the working principle of the high-pressure cleaner ? Next we will work together to understand the working principle of the pressure washer !
Pressure washer working principle
High-pressure cleaners use water as the working medium and consist of a booster pump and a power drive unit. Usually, a power-driven pump completes a suction and discharge process for water, converting ordinary water into high-pressure, low-flow water. It is then sent to the high pressure line so that it reaches the high pressure nozzle with a certain amount of energy. The aperture of the high pressure nozzle is much smaller than the diameter of the high pressure line, so the water reaching the high pressure nozzle must be accelerated in order to pass through the nozzle. In this way, the nozzle can turn the high pressure, low flow rate water into a low pressure, high flow rate jet.
The size of the water flow can be controlled in three ways, by increasing or decreasing the inner diameter of the pump head, by lengthening or shortening the stroke of the plunger. By increasing or slowing the reciprocating speed of the plunger. Most pressure washers use a set of valves and pump heads to form a system. The plunger pulls water into the inlet valve and pressurizes it through the outlet valve. The valve controls water through the pump by preventing backflow. The valve consists of a spring and a bracket, and the pressure operation is completed due to different pressure differences on both sides of the valve. When the pressure on the valve is greater than the capacity of the spring, the valve opens.
On the opposite stroke, water will automatically squeeze the bracket onto the seat, keeping the valve closed and preventing backflow. The jetted high-pressure water jet tangentially or forwardly impacts the surface of the object (workpiece) being cleaned as a jet operation. High pressure water jets are the simplest form of energy conversion and application. When the impact force of the high-pressure water jet is greater than the adhesion between the dirt and the surface of the object, the dirt will be peeled off, washed away, and a cleaning device for cleaning the surface of the object is achieved. Because high-pressure cleaners use high-pressure water column to clean the dirt, the high-pressure cleaner is also one of the world's most recognized scientific, economic, and environmentally friendly cleaning methods.
Classification of pressure washers
1, according to use classification: According to use classification, can be divided into home, commercial and industrial use three. In general, high-pressure pipe dredging machines for home use general pressure to meet the demand, and their flow and life are relatively low. This type of pipe dredging machine is easy to carry, easy to move, and flexible in operation. Commercial high-pressure pipe dredging machines have higher requirements on parameters, frequent use times, and long service life, so they usually have long service life.
2, according to the difference in the temperature of the water to be classified: according to the different temperature of the water to be classified, high-pressure pipe dredging machine can be divided into cold water high-pressure pipe dredging machine and hot water high-pressure pipe dredge two. A heating device is added to the hot water high-pressure pipe dredging machine. Usually, a combustion cylinder is used to heat the water. The use of hot water washing can quickly flush a large amount of dirt and oil that cold water does not easily wash out, so that the cleaning efficiency is unprecedentedly improved. However, because of the high price and high operating cost of hot water high-pressure pipe dredging machines, most users often purchase ordinary cold water high-pressure pipe dredging machines.
3, according to the different types of drive engines to be classified: according to the different types of drive engines to be classified, can be divided into gasoline engine driven high-pressure pipe dredging machine, motor-driven high-pressure pipe dredging machine and diesel-driven pipeline dredging machine three. All three types of pipe dredging machines are equipped with high-pressure plunger pumps, which are respectively connected with gasoline engines, motors or diesel engines, thereby driving the high-pressure pumps to work. The salient advantages of gasoline-powered high-pressure pipe dredging machines and diesel-powered pipe dredging machines are that they can operate normally in the field without the need for power.
With regard to the working principle of the pressure washer , I introduced it to you, and I hope to help you, and I would like to look forward to seeing more information on this site.
